A method for making a playlist available to the public, in which the playlist comprises user-defined descriptor information. The user-defined descriptor information is entered as free form text or prose.

A method of restricting data access based on properties of at least one of a process and a machine executing the process includes receiving, by an access control management system, from a first computing device, information associated with an encrypted data object. The method includes requesting, by the access control management system, from a verifier, verification that a second computing device executes a process in accordance with a process attribute identified in the information associated with the encrypted data object. The method includes sending, by the access control management system, to the second computing device, the received information associated with the encrypted data object, responsive to the verification of the process attribute.

A method is provided for securely providing data for use in a consumer electronics device having a processor performing instructions defined in a software image. The method includes receiving the data encrypted according to a global key, further encrypting the data according to a device-unique hardware key, storing the further encrypted data in a secure memory of the consumer electronics device, providing the global key to a whitebox encoder for encoding according to a base key to generate a whitebox encoded global key, and transmitting the software image to the consumer electronics device for storage in an operating memory of the consumer electronics device, the software image having a whitebox decoder utility corresponding to the whitebox encoder and the whitebox encoded global key.

Techniques for providing segments of media items associated with events to users are described herein. Computing device(s) may receive from a user a request for a segment of a media item associated with an event. The computing device(s) may also receive data presented as evidence of acquisition of a pass for the event, verify that the data is associated with a valid pass that has been purchased for the event, and, based on the verifying, provide the segment of the media item to the user. Additionally or instead, the request may include a time length for the segment and/or a beginning position of the segment, and the computing device(s) may determine, based on a policy and one the time length and/or beginning position, a part of the requested segment of the media item to provide. The computing device(s) may then provide the determined part of the segment to the user.

A security system is disclosed in which a secure communication session is established between an external security processor and an interface device. After insertion of the external security processor into the interface device, an authorization server provides authorization to the external security processor and the interface device based on, for example, identification information for each device. A derived key may be generated using a common device security key, and a seed value stored at the interface device. The derived key may then be used for multiple communication sessions between the interface device and the external security processor.

There is provided a method for use by a playback system to play back encrypted content associated with a first globally unique identifier (ID). The method includes storing an encrypted content in a memory being under control of a memory controller having a second globally unique ID, storing the first globally unique ID, transmitting a request from the memory controller to a license server, the request comprising the first globally unique ID, the second globally unique ID and a request for a content license to play back the encrypted content, receiving the content license enabling a right for the playback of the encrypted content, the content license including content keys and being encrypted to be decryptable according to a memory controller secret associated with the second globally unique ID, decrypting the content license, according to the memory controller secret to recover the content keys to a playback module.

A method, apparatus, and system for detecting a video bitstream, and a non-transitory computer-readable storage medium are disclosed. The method may include: receiving a first feature value generated by a source node which transmits a video bitstream, where the first feature value is feature information of the video bitstream generated by the source node according to a preset rule; receiving a second feature value generated by another node which transmits the video bitstream, where the second feature value is feature information of the video bitstream generated by the another node according to the preset rule; determining whether the first feature value is consistent with the second feature value via comparison; and generating an alarm in response to a comparison result that the first feature value is inconsistent with the second feature value.

Electronic publications are increasingly replacing physical media but to date standards have evolved to mimic these physical media. Accordingly it is beneficial to provide electronic publication software systems and/or software applications to enable new paradigms that provide consumers, authors, publishers, retailers, and others with new models for releasing digital content from editorial and authorship viewpoints; new models for providing digital rights management with licensing, re-assignable rights and the ability to issue sub-rights or issue partial licenses with predetermined validity; new models for publishers to release revised editions, errata, new additions, etc; engaging social network type collaborative behavior within work and private environments with associated content (annotations) to the original release content; and supporting discussion and information dissemination within a wide variety of environments from education to business to book clubs etc. The invention also supports distributing electronic content with fingerprinting allowing unique identification of sources of non-authorised content.

A system for providing mobile content to a mobile communication device includes a first computing system including one or more servers to cause a graphical user interface to be displayed at a second computing system, the graphical user interface (i) enabling a user of the second computing system to at least one of create, edit, or select the mobile content and (ii) enabling the user of the second computing system to provide a phone number associated with the mobile communication device, the mobile communication device being separate and remote from the first computing system and the second computing system. The first computing system uses the phone number to cause delivery of the mobile content to the mobile communication device via a wireless communications network in a format compatible with one or more operational parameters of the mobile communication device, the one or more operational parameters including at least one of a mobile communication device type and a software platform type, wherein the using of the phone number to cause the delivery of the mobile content to the mobile communication device is performed without the mobile communication device identifying the one or more operational parameters to the first computing system or the second computing system.

A method and computer readable medium for exploring similar users and items of a media service includes generating a user interface. The user interface displays a user selectable indicia representing a similar member function for allowing a user to search a media service for at least one other user. The one other user has a degree of similarity with respect to the searching user. Another method includes facilitating the search of such a similar user within a media service.
